Fixphonon

WebFix-phonon - FixPhonon: An extension to LAMMPS for the evaluation of phonons. This project presents an implementation of the method to evaluate the phonon dispersion … WebThis package contains a fix phonon command that calculates dynamical: matrices from finite temperature MD simulations, which can then be: used to compute phonon dispersion relations, directly from molecular: dynamics simulations. See the doc page for the fix phonon command for detailed usage instructions.
